IMPROVEM ENT IN EARTH-CLOSE'I;S.

Specification forming part of Letters Pat-ent No. [07,451, dated September 20, 1870.

To all whom it may concern:

Beit known that I, LEWIS G. CLOCK, of Manchester,in the county of Hillsborough and State ot'New Hampshire, have made a new and useful Invention having reference to Earth- Closets; and I do hereby declare the same to be-fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a longitudinal and vertical section, Fig. 2 a horizontal section, and Fig. 3 a rear elevation, of an earth-closet provided with my invention.

ln the drawings the hod or excrement and Vurine receiving vessel is shown at A as open both at top and bottom, it being provided at the latter with a valve, B, which is xed to an arm, a2, projecting from a vertical shaft, C. The said shaft, supported in bearings a a, has a crank or arm, 1 1, extended horizontally from its upper end. By taking hold of the crankb and moving it so as to turn the shaft C the valve may be moved asidefrom underneath the open bottom of the receiver A. Such receiver may be supposed to be arranged over a vault or a passage leading thereto, or to a proper place for the reception of the deposits made in and discharged from the vessel Ai'rom time to time.

An inclined chute o r conduit, D, arranged to discharge into the rear part of the said vesselA, has its bottom, at its discharging end, furcated or notched in manner as shown at c in Fig. 4, which is a top view of such bottom. Ihave found that when the bottom is so notched the earth discharged by it will be thoroughly disseminated over the excremental deposit, or in a far better manner than will be the case when the bottom is without a notch or has a straight front end.

Over the vessel Ais the seat E, which at its rear edge is hinged to the closet-frame F so as to be capable of being turned from a horizontal up into a vertical position. The seat-hole is shown at d, there being fixed to the seat so as to extend down from it a circuit-shaped delector or guard, Gr, which, when the seat is at itslowest position, projects into the hod or vessel A, and is intended to .deflect into the said vessel the urine that may be discharged from a person while sitting upon the seat, the deector operating to prevent the urine from being ejected over and beyond the frontof the upper edge ofthe vessel A. The cover of the seat is represented at H, it being hinged to the frame F. In the upper part of such frame F is a hopper, I, which at its rear is fixed to a horizontal bar, K, and at its front to another but longer bar, L, such bars being arranged as represented. The shorter of such barsthat is, the bar K-is connected with two stationary brackets, M M, by hinges ec. Beneath the front bar, L, are two vertical slides or pitmeu, N N, which at their lower ends rest on the rear arms ot1 two levers, O O, on whose irst arms the seat E rests, each of suchlevers having'its fulcrum disposed with respect to it as shown atj'. The rear arms of the pair of levers O O are constructed so as to forni a weightbox, P, for the reception of one or more weights, lt.

Connection-bars S S, pivoted tothe weightbox, extend upward and are jointed toarockerframe, T, arranged between and having its pivots supported by the brackets M M.

To the said rocker-frame two horizontal slides, U V, are hinged, they being arranged with such frame so as to be capable of sliding horizontally into and out of the vertical portion W of the chute, such vertical portion leading from the bottom of the hopper.

A person in the act of sitting upon the seatwill depress it and so move the levers O O as to cause the rocker-frame to be moved in one direction in a manner to force the lower slide, V, into and across the conduit W, the slide U at .the same time being drawn backward so as to allow a charge from the hopper to descend upon the slide V. On the person rising from the seat the weight in the weight-box will move the levers in an opposite direction, whereby the movements of the sliders U V will be reversed-that is to say, the upper one will be vto tilt the hopper in order that the contents N, with the hopper pivoted to its supports, as described, and with the levers O O, arranged With the seat, pivoted to the frame, as set forth.

4. The combination of mechanism for tip ping the hopper, in manner as described, with such hopper, its chute, the two slides N N, and their operative mechanism, arranged with and to be actuated by the seat and a weight, as explained.
